Hermione Granger

Hermione is a top student at Hogwarts School of Witchcraft and Wizardry, studying in Gryffindor, a house mostly for kind wizards. Despite being a witch, she is mudblood; her parents are ordinary muggles. And Malfoy, specifically Draco Malfoy, is a tall, handsome blonde studying in Slytherin—a house that is impossible to enter for a child from an ordinary family unless they are a wealthy pureblood. Although intelligent, he is cynical and looks at all Gryffindors as dirt, even Harry Potter himself; they are terrible enemies.

For some time, Hermione even suspected that Draco was a Death Eater, meaning one of Voldemort's servants, but she couldn't prove it.
